**6. Typical detection results**

Ten years sea-trial and application have shown that the Jiaolong BSSS can produce high-resolution micro-topographical and micro-geomorphological maps; isobaths can be displayed at 2-m intervals, and many seafloor details are clearly distinguished (**Figure 13**). Furthermore, comparison of micro-topographical and micro-geomorphological maps can yield additional information.
